Title: Method for recovering oil from a subterranean oil containing formation
Inventor: DJABBARAH NIZAR F
IPC: E21B43/24
Filed: 1993-11-12
Granted: 2003-09-23
Abstract: The invention is a foam method for improving conformance during a steam flood or carbon dioxide flood in a subterranean, oil-containing formation penetrated by at least one injection well and at least one production well. In a steam flood oil recovery process, sweep efficiency is improved by injecting steam until steam breakthrough occurs at the production well after which a mixture of steam, a noncondensible gas, and an aqueous surfactant-starch solution is injected into the formation. The aqueous surfactant-starch solution forms a stable foam with the formation oil at formation conditions that reduce the permeability of the highly permeable steam swept zones thereby diverting the steam to other portions of the formation containing unswept oil. The starch is used as a partial substitute for the surfactant to improve the cost of the foam-forming mixture without reducing its effectiveness in increasing sweep efficiency.

Title: Improved thin-film structure for chalcogenide electrical switching devices and process therefor
Inventor: KLERSY PATRICK J
IPC: H01L45/00
Filed: 1992-07-16
Granted: 2002-11-19
Abstract: Disclosed herein is a novel thin-film structure for solid state thin-film electrical switching device fabricated of chalcoge-nide material that overcomes a number of design weaknesses existing in the prior art. The novel structure of the instant invention employs a thin layer of insulating material (16) beneath the body of chalcogenide material (3) so as to carefully define the fila-ment location. Since the filament location has been fixed, switching, due to edge conduction pathways has been substantially eli-minated. At the same time, the use of a thin insulating layer precludes step coverage faults of the prior art. The requirement for the thin layer of insulator material to withstand the switching voltage is addressed through the use of a second thicker layer of in-sulator material (2) which is deposited only after the chalcogenide material (3) has been formed. This improved structure demon-strates the advantages of higher fabrication yields and more repeatable electrical switching characteristics.

Title: Mobile-synchronized handoff in a wireless communications system
Inventor: FARWELL CHARLES YEOMANS
IPC: H04W36/36
Filed: 1994-07-07
Granted: 2000-05-16
Abstract: An arrangement for effecting call handoffs in a wireless communications system (FIG. 1) in a substantially glitchless manner. The arrangement relies on the mobile terminal (4) that is involved in a handoff to trigger the handoff by transmitting a handoff coordination signal simultaneously to the base stations (l, 2) that are involved in the handoff. The base stations receive the signal substantially simultaneously, and in response the base station that has been serving the mobile terminal's call ceases to do so while the base station that is henceforth to serve the mobile terminal's call commences to do so at the same instant in time.

Granted: 1999-02-23
Abstract: For recording or reproduction of  information,  the optical beam is moved relative to the recording medium along the  longitudinal  direction  of  a  certain  track.    When accessing another track, the relative  movement of the light beam  along  the  longitudinal  direction of  the  track  is decelerated, and during this deceleration, the light beam is started to move in the direction transverse to the tracks toward the desired track.  Thus, it is not necessary to wait for such time when the relative  movement of the light beam along the longitudinal direction of the track has been completely stopped, and hence the necessary accessing time can substantially be reduced.  If control is made to cause a decelerating rate of the relative  movement to decrease continuously gradually or stepwise from a relatively high decelerating rate to a relatively low rate and the light beam is caused to start relatively moving toward the desired track while the relative  movement is at the relatively low decelerating rate,  it is allowed to effectively suppress occurrence of unwanted  mechanical vibration due to abrupt deceleration of the relative  movement.
